Beach Ball

Throwing one turns it into a physical object that lives in the world until it settles down and you pick it back up. Blocks, doors and liquids all bounce it. Players do not: walking into the ball punts it away, and a running player can send it clear off the screen. Anything that flies or fires counts too, so pets and minions will keep a ball in the air on their own while you stand there watching.

Keep it off the ground past ten hits and the game starts announcing the count to everyone in the world. That is the entire game with it, and it works best with a few people trading volleys in a room with a wall at each end. Throw several at once and they collide with each other as well.

• The game files it as a projectile, which is enough to trip a Teal Pressure Pad. You can wire a goal that scores itself.
• Play near the edge of the world and you will simply never see that ball again. Furniture and town NPCs are also invisible to it, so it passes through them without a bounce.
